As for radios, first with 8 worker stations plus the other people requiring them Highlands had to commandeer several personal radios to come up with enough. there were still a couple people that could have used a radio: grid, etc.. Putting the starter on another channel would have required the computer operator to deal with 2 radios, entering cars and penalties and dealing with operational issues like misbehaving software and wireless timers (Shane ran the computer for most heats and was busier than a 1 armed paper hanger) The disadvantage of their wireless system in addition to the obvious was that a timer display could not be connected at the same time. This required a person to sit at the finish and write times on a board. Those times were radio relayed by the person doing raw sheets. With 8 worker stations, starter, and OD on the same frequency calls were being stepped on constantly, and I suspect the course workers were dropping their radios to their sides after making the call and not hear a request for a repeat on a call. One more timing and scoring person would have been a big help.
Getting workers out on course was a problem because the paddock was so far away. The PA would not carry that far and their FM transmitter also crapped out on Sat.
AXware ate all the times for the first heat on Sat so all those times had to be reentered from the raw sheets after the event on Sat.
Note I am relaying all this to hopefully to learn from it, not to be critical. Sunday's course was one of the best I have run at Danville IMHO, and we had a blast despite the weather. Next time tent city will be in our trailer as we should have the AC installed by then.
